Superfluid helium or He II is a macroscopic quantum fluid that exhibits extraordinary properties. %By applying the limit of low flow velocities, The behavior of the fluid can be understood using a Landau - Tisza model, where He II is considered to be a two-component fluid with independent velocity fields: the inviscid superfluid of density $\rho_s$, and the normal fluid of density $\rho_n$, where the total density $\rho$ = $\rho_s$ + $\rho_n$ \cite{Tisza,Landau}. The superfluid has neither…

The purpose of our investigation is to find the most efficient way to recycle cans( make them self- implode) to help the Oakland Recycling Center find the best process for them to recycle aluminum. This problem is important because it is important for us to start recycling cans in order for global warming to decrease in the world. Not recycling cans means that new aluminum cans will have to be made, and to make new aluminum cans people have to dig into the earth’s crust which wastes a lot of…

Some scientist didn’t believe that the popping noise had anything to do with gas bubbles. To follow up on this hypothesis, some scientist used an MRI to prove the “gas bubble theory” wrong. First, scientist had studied 10 joints by using volunteers’ fingers into a tube. They did this so they could apply traction to the joint. They had specifically used the metacarpophalangeal joints because those were the most common joints that people crack. Then, they took images before and after cracking the…

It begins on a 6 acre piece of land as an oil rig, with other large machinery and generators. The process includes injecting a mixture of water, sand, and chemicals at a high pressure to break shale rocks and release the natural gas inside. Amongst many shale formations in the U.S., the shale area that spreads from eastern Ohio to western Pennsylvania is called Marcellus. The shale rocks are nearly 5,000 to 8,000 feet underground…

difference in initial pressure inside the bottle rocket and the atmosphere, and the vertical height reached by the bottle rocket after 0.1 seconds, is proportional. This is quantitatively demonstrated by the high R2 value of 0.99533 of the graphed relationship, which indicates the likeness of points in a data set to an established trend; where 1 = a perfect relationship. The gradient of 0.0236 in the best fit regression line of the data, indicates that for every increase of 1 PSI in pressure…

ingenious experiments called “Opinion and Social Pressure”. Asch discovered by doing these experiments that individuals can be persuaded by a group of people to deny your own sense. Over the years Asch got the information to provide a powerful explanation on how people will forget their own sense and judgment to their peers. In “Opinion and Social Pressure” Asch did many experiments to figure out what the effect would be on if a group pressures an individual throughout a series of tests. Asch…

Abstract: This research will be an overview about what are the pressure related dangers of scuba diving, how do these dangers happen, how to prevent those dangers and the identification of their symptoms. Introduction: A form of underwater diving with the use of breathing apparatus to breathe underwater is Scuba Diving. Great freedom of movement and longer underwater endurance can be felt for diving with their own or personal source of breathing gas which contains compressed air rather than…

The valves were set up so that the water would flow from Tank 2, through the ½” nominal diameter, type L copper pipe, through the needle valve WV5 (Appendix A), and back to Tank 2. WV5 was initially closed. The Honeywell STD 924 DP meter’s pressure tap lines were placed at PT 1, just before the P-1 Sterlings Fluid System Peerless Pump PE50B1, and PT 10, just after WV5. A Fluke 179 multimeter was attached to the DP electrical box. The multimeter was set to read electrical signal in the form of…

Many young people receive a significant volume of pressure to live up to their families ' expectations. Additionally several parent expectations can damage a child 's self-confidence, self-image, and mentality. Even if the parent means well, children can perceive their good intentions in a different manner. As a Mexican-American Richard Rodriguez felt pressure from his mom and other family members to shield his dark skin from the sun, he speaks on his insecurities in Complexion. Rodriguez…

NTRODUCTION In this experiment the validity of Gas Laws were observed and the relationship of two variables, temperature and volume, against pressure was tested. Gas Laws are encompassed by the Ideal Gas Law in which PV=nRT observes the general behavior of a gas under ideal conditions in terms of pressure(P), volume(V), moles of gas(n), gas constant(R), and temperature(T). The Ideal Gas Law is a combination of Boyle 's Law, Charles ' Law and Avogadro 's Law and was first introduced in 1834 by…
